It highlights the significance of monohybrid crosses and includes advancements made by Harriet Creighton and Barbara McClintock in 1932 regarding chromosome recombination.

But humans are not either tall or short nor are they either heavy or light. Many traits differ in a continuous, quantitative way throughout a population. This can be explained by assuming it is controlled by several pairs of genes — called quantitative trait loci (QTL) — the effects of which are added together (called polygenic inheritance).
